SwitchA(config)# interface ethernet 1/5

SwitchA(config-if-eth1/5)# channel-group 100 mode active

SwitchA(config-if-eth1/5)# exit

SwitchA(config)# interface ethernet 1/6

SwitchA(config-if-eth1/6)# channel-group 100 mode active

SwitchA(config-if-eth1/6)# exit

Configure MC-LAG Domain 1:

SwitchA(config)# mclag domain 1

SwitchA(config-mclag-domain)# peer-link port-channel 100

SwitchA(config-mclag-domain)# local-ip 192.168.1.1

SwitchA(config-mclag-domain)# peer-ip 192.168.1.2

SwitchA(config-mclag-domain)# system-mac 00:00:00:11:11:11

SwitchA(config-mclag-domain)# exit

Save Configuration:

SwitchA# write memory

Comprehensive Detailed Step by Step Explanation with References:

Enter Configuration Mode:

Begin by entering the global configuration mode to make changes to the switch configuration.

Create VLAN 101:

Create VLAN 101 to be used for the MC-LAG peer link communication.

Create Port-Channel 100:

Enter the port channel interface configuration mode using interface port-channel 100.

Set the port channel to trunk mode with switchport mode trunk.

Allow VLAN 101 on the trunk with switchport trunk allowed vlan 101.

Exit the port channel interface configuration mode.

Assign Physical Interfaces to Port-Channel 100:

Enter interface configuration mode for ethernet 1/5 and assign it to port channel 100 using the channel-group 100 mode active command.

Exit the interface configuration mode.

Repeat the same steps for ethernet 1/6.

Configure MC-LAG Domain 1:

Enter the MC-LAG domain configuration mode using mclag domain 1.

Specify the peer link port channel with peer-link port-channel 100.

Configure the local IP address as 192.168.1.1 using local-ip 192.168.1.1.

Configure the peer IP address as 192.168.1.2 using peer-ip 192.168.1.2.

Set the MC-LAG system MAC address using system-mac 00:00:00:11:11:11.

Exit the MC-LAG domain configuration mode.

Save Configuration:

Save the configuration to ensure the changes persist after a reboot using the write memory command.

These steps provide a comprehensive guide to configure the peer link for an MC-LAG scenario on SwitchA, ensuring the specific requirements for IP addressing, VLAN configuration, and port channel setup are met.

Here are the steps to create the VTEP and map the VNI to the VLAN:

Enter Configuration Mode:

SwitchA# configure terminal

Create VTEP Interface:

SwitchA(config)# interface vtep1

SwitchA(config-if-vtep1)# ip address 10.10.10.1/24

SwitchA(config-if-vtep1)# exit

Map VNI 400 to VLAN 40:

SwitchA(config)# vlan 40

SwitchA(config-vlan)# vn-segment 400

SwitchA(config-vlan)# exit

Enable ARP Neighbor Suppression:

SwitchA(config)# interface Vlan40

SwitchA(config-if-Vlan40)# ip address 192.168.40.254/24

SwitchA(config-if-Vlan40)# vxlan arp-suppression

SwitchA(config-if-Vlan40)# exit

Save Configuration:

SwitchA# write memory

Enter Configuration Mode:

Begin by entering the global configuration mode to make changes to the switch configuration.

Create VTEP Interface:

Enter the interface configuration mode for the VTEP interface named vtep1 using interface vtep1.

Assign the IP address 10.10.10.1/24 to the VTEP interface using the ip address command.

Exit the interface configuration mode.

Map VNI 400 to VLAN 40:

Enter the VLAN configuration mode for VLAN 40 using vlan 40.

Map the VNI 400 to VLAN 40 using the vn-segment 400 command.

Exit the VLAN configuration mode.

Enable ARP Neighbor Suppression:

Enter the interface configuration mode for VLAN 40 using interface Vlan40.

Assign the anycast IP address 192.168.40.254/24 to the VLAN interface using the ip address command.

Enable ARP neighbor suppression using the vxlan arp-suppression command.

Exit the interface configuration mode.

Save Configuration:

Save the configuration to ensure the changes persist after a reboot using the write memory command.

Here are the steps to configure the required port channel and VLAN settings on Switch A:

Enter Configuration Mode:

SwitchA# configure terminal

Create Port Channel 10:

SwitchA(config)# interface port-channel 10

SwitchA(config-if-po10)# switchport mode trunk

SwitchA(config-if-po10)# switchport trunk native vlan 1

SwitchA(config-if-po10)# switchport trunk allowed vlan 1,10

Assign Interfaces Eth 1/11 and Eth 1/12 to Port Channel 10:

SwitchA(config)# interface ethernet 1/11

SwitchA(config-if-eth1/11)# channel-group 10 mode active

SwitchA(config-if-eth1/11)# exit

SwitchA(config)# interface ethernet 1/12

SwitchA(config-if-eth1/12)# channel-group 10 mode active

SwitchA(config-if-eth1/12)# exit

Configure Interface Eth 1/1 for Server Connection:

SwitchA(config)# interface ethernet 1/1

SwitchA(config-if-eth1/1)# switchport mode trunk

SwitchA(config-if-eth1/1)# switchport trunk native vlan 1

SwitchA(config-if-eth1/1)# switchport trunk allowed vlan 1,10

SwitchA(config-if-eth1/1)# end

Save Configuration:

SwitchA# write memory
